SEPARATOR.

Application filed February 11, 1928. Serial No. 258,788.

This invention relates to a separator for removing foreign matter fromcotton, the general object of the invention being to pro videa-vertically arranged casing havmg its 5 upperend connected to the trunkline of the cleaning systemso that the suction 1n the line will create asuction in the casing, the casing havin anairinlet at its lower end,with means or delivering the cotton to. the

casing from the cleaner in such a manner that the foreign matter entersthe casing be low the cotton so that the air passmgupwardly through thecasing lifts the cotton away from insteadof through th1s foreign matter.v 7

Another object of the invention is to pro vide an adjustable bafileplate in the casing for regulating the. air passage therethrough, thebaflle; having a perforated plate 111 its lower end with a catch boxback of the plate so that particles of foreign matter, striking theplate, will pass through the perforations therein into the box.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, il-

lustrated in the accompanying drawings and s ecifically pointed out inthe appended c aims.

In describing my invention in detail,reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which 2- Figure1 is an end view showing the improved separator attached to the cleanerdevice of the cotton cleaning system.

Figure 2 is an elevation.

Figure 3 is a section on line 33 of Figure 2.

Figure 4 is a section on line 44 of Figure 3.

Figure 5 is a section on line 5--5 of Figure 3.

In these views, the numeral 1 indicates the vertically arranged casingwhich forms the body of the separator, said casing having its front sideopen and its lower part enlarged. A baffle plate 2 closes the front ofthe casing, except the lower part thereof, so as to provide an air inlet3. The upper end of the baflle plate is hinged to the front upper end ofthe casin as shown at 4, and said plate is adjustab e through means ofthe lever 5 hinged to the front part of the plate and having notchestherein, any one of which is adapted to receive an edge of anangle-shaped cross piece 6 attached to the front edges of the casing.The lower part of the plate is formed with an opening 7 which is coveredby a perforated late 8 and a catch box 9 is attached to the rout of theplate 2 and covers the opening. This catch box is provided with a hingedbottom '10 which is normall held closed by the weight on the arm 11. Theupper end of the casing is adapted to be connected to the trunk line ofthe system leading to the condenser so that a suction is created in thecasing which draws air through the inlet 3 a part of this trunk linebeing shown at 14. The dischar chute 12 of the cleaner cylinder, locatedin the casing 13, is attached to the lower part of the casing, ata pointopposite the perforated plateS of the bafile plate 2, and as showninFigure 1, this chute extends downwardly at an angle from the bottomlevel of the cylinder;

From the foregoing it will be seen that the cotton and the heavy oreignmaterials therein are discharged from the cleaner screen or cylinderinto the separator casing. The centrifugal force set up in the cleanercauses the heavy materials to be discharged into the casing 1 below thecotton discharged into said casing and the air passing upwardly throughthe casing 1 lifts the cotton away from this heavy material. The heavymaterials also leave the cleaner, traveling at much higher speed thanthe cotton and resent a smaller proportionate area upon w ich the aircan act. Thus there is no danger of this material being mixed with thecotton in the separator casing. The cotton striking the baflle plate 8will be freed from certain small particles of material which pass intothe box 9 and which would otherwise pass upwardly through the separatorwith the cotton. As soon as the amount of material in the catch boxoverbalance's the weight on the arm 11, the bottom will drop and thusautomatically empty the box. This catch box and bafile plate rids thecotton of fine leaf, etc., which would otherwise pass upwardly with thecotton. called to the fact that the air is drawn from the room into theopening 3 and not through the cleaner casing 13, thereby avoiding asuction in the cleaner cylinder which would interfere with't-he actionof the vanes on the cotton.; a

It will, of course, be understood that the heavy materials passing intothe separatorcasing from the cleaner screen or cylinder Will drop to thebottom ottheseparator casing from which it may be removed thronglr.

the opening 3 and the materials passing into the catch box throu 'h thebaffle )lateare alsoremoved through said opening.

. Itis thought fromthe foregoing-descrip-v tion thatthe advantages andnovelleatures .of m invention-will'be readilv a-marent.

Iti's to-be understood that I may make changesin ther construction andin the combinationi and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.

' -What I claim is 1. Aiseparator'for a cotton-cleaning tem includinga-cleaner and a trunkline-lead ingtothe condensercomprising averticallly arranged casing;having its upper'end connected with 'thetrunk line-and having an air inlet at its bottom; a vertically arrangedbaffle pIate-in-the casing-,- means for adjusting the-:plate: toregulate the size of the -air pas- I sage through the casing and meansfor conair inlet at its bottom, a vertically arranged baflle plateinthe.-casing,;means fOIl adjusting the plate to regulatethe-size of theair passage through the casing, means for con nectingthe lowerpart ofthe casing with the cleaner of the system at a point below the bottom ofthe cleaner cylinder, said baffle plate having an opening in its lowerend arranged opposite the discharge from the cleaner cylinder aperforated plate covering the opening-- and a catchboX- on the baffleplate for receiving material passingrthrougli the perforations intheplate.
